Communicative skills in Spanish children with Autism Spectrum Disorder and children with Attention Deficit Hyperactivity Disorder. Analysis through p…
2018
Background Communicative skills are one of the main deficits experienced by children with Autism Spectrum Disorder (ASD). The differential diagnosis is a complex issue that clinicians often face. For this reason, this study has two objectives: 1) to analyze the similarities and differences that children with Attention Deficit Hyperactivity Disorder (ADHD) and children with ASD present in their linguistic and communicative skills, through parentś perceptions and narrative production; 2) to identify the relative importance of the skills analyzed in discriminating children with ASD versus children with ADHD, as well as the classification power of each of the two measurement methods used. Metho…
Cuidado y responsabilidad: de Hans Jonas a Carol Gilligan
2019
El objetivo de este trabajo es situar la ética del cuidado en contexto de las éticas de la responsabilidad. Para ello analizamos la orientación hacia el cuidado en las éticas de la responsabilidad mostrando la transición de una responsabilidad limitada por el cálculo consecuencialista en la actividad política, a una responsabilidad integral exigida por la preservación de la naturaleza ante los desafíos de la ciencia y la técnica. Interpretamos la aportación de Carol Gilligan en términos de «provocación » a la ética contemporánea para que el cuidado no sea únicamente una categoría sentimental o afectiva sino una categoría con la que reconstruir reflexivamente la justicia social. Esta interpr…
A Navigation and Augmented Reality System for Visually Impaired People
2021
In recent years, we have assisted with an impressive advance in augmented reality systems and computer vision algorithms, based on image processing and artificial intelligence. Thanks to these technologies, mainstream smartphones are able to estimate their own motion in 3D space with high accuracy. In this paper, we exploit such technologies to support the autonomous mobility of people with visual disabilities, identifying pre-defined virtual paths and providing context information, reducing the distance between the digital and real worlds. In particular, we present ARIANNA+, an extension of ARIANNA, a system explicitly designed for visually impaired people for indoor and outdoor localizati…
A basic need theory approach to problematic Internet use and the mediating effect of psychological distress
2015
The Internet provides an easily accessible way to meet certain needs. Over-reliance on it leads to problematic use, which studies show can be predicted by psychological distress. Self-determination theory proposes that we all have the basic need for autonomy, competency, and relatedness. This has been shown to explain the motivations behind problematic Internet use. This study hypothesizes that individuals who are psychologically disturbed because their basic needs are not being met are more vulnerable to becoming reliant on the Internet when they seek such needs satisfaction from online activities, and tests a model in which basic needs predict problematic Internet use, fully mediated by p…
Feminisme neoliberal: un oxímoron?
2018
Neoliberal Feminism: An Oxymoron? Resum: En el present escrit tractem d’aproximar-nos al concepte de “feminisme neoliberal” per tal d’identificar-ne les principals caracteristiques i contradiccions. Aixi doncs, l’objectiu principal que ens plantegem tracta de discernir si es possible, atenent al context actual de desenvolupament del moviment feminista en un marc neoliberal, parlar de “feminisme neoliberal”, o si pel contrari, es tracta d’un concepte que es en si mateix un oximoron. Partint del sentit de transformacio social cap a la justicia intrinsec al moviment feminista, tractarem de veure com la logica neoliberal ha condicionat o influenciat en aquest moviment en l’actualitat. Alhora es…
Energy efficient resource allocation in heterogeneous software defined network: A reverse combinatorial auction approach
2015
In this paper, resource allocation for energy effi- ciency in heterogeneous Software Defined Network (SDN) with multiple network service providers (NSPs) is studied. The considered problem is modeled as a reverse combinatorial auction game, which takes different quality of service (QoS) requirements into account. The heterogeneous network selection associated with power allocation problem is optimized by maximizing the energy efficiency of data transmission. By exploiting the properties of fractional programming, the resulting non-convex Winner Determination Problem (WDP) is transformed into an equivalent subtractive convex optimization problem. The proposed reverse combinatorial auction ga…
Performance Evaluation for a Sustainable Supply Chain Management System in the Automotive Industry Using Artificial Intelligence
2020
Increasing the sustainability of a system can be achieved by evaluating the system, identifying the issues and their root cause and solving them. Performance evaluation translates into key performance indicators (KPIs) with a high impact on increasing overall efficacy and efficiency. As the pool of KPIs has increased over time in the context of evaluating the supply chain management (SCM) system&rsquo

Nicotinic receptor agonists as neuroprotective/neurotrophic drugs. Progress in molecular mechanisms
2007
In the present work we reviewed recent advances concerning neuroprotective/neurotrophic effects of acute or chronic nicotine exposure, and the signalling pathways mediating these effects, including mechanisms implicated in nicotine addiction and nAChR desensitization. Experimental and clinical data largely indicate long-lasting effects of nicotine and nicotinic agonists that imply a neuroprotective/neurotrophic role of nAChR activation, involving mainly alpha 7 and alpha 4 beta 2 nAChR subtypes, as evidenced using selective nAChR agonists. Compounds interacting with neuronal nAChRs have the potential to be neuroprotective and treatment with nAChR agonists elicits long-lasting neurotrophic e…
